Determinants of Consumer Purchasing Intention toward Energy-Efficient Bulbs 1. Introduction Light usage is considered to be almost 20 percent of the world's produced electricity. So, this percentage can be saved by using energy efficient bulbs instead of incandescent bulbs, since efficient bulbs tend to last longer, consume twothirds less energy, and produce less heat by 70 percent. Therefore, using efficient bulb have a lot of advantages since it eliminates greenhouse effect, reduce energy cost and save the environment, which are very important issues. Although, replacing incandescent bulbs by energy efficient bulbs is vital, they are not fully adopted. Many governments have tried to promote the switch of bulbs, and some ways by banning the incandescent bulbs which are energy-inefficient and trying to substitute them with other energy saving technologies like LEDs (Uddin S, Shareef, 2013). Then when comparing incandescent bulbs with energy efficient bulbs, the result will be that the energy efficient bulbs are less costly and better on the environment, so it saves both money and the environment. Therefore, we conducted this study with the aim of identifying, examining and better understanding the "Factors That Affects Energy-Efficient Bulbs Purchase Intention". This study will evaluate these factors with respect to the point of view of the consumers, in order to understand which factors specifically influence consumers to acquire specific attitudes that influence the purchase of energy-efficient bulbs. Hence, for the purpose of analyzing consumers perceptions, and its link with other factors, different models of attitude will be applied. This research intentions are to explore the reasons that impact the purchasing intentions of energy-efficient bulbs, this section provides an overview, and covers the research objectives, research problem, research questions and research importance. Therefore, the research aims first to find out the determinants of energy efficient bulb purchase intention to help policy makers in expressing and executing strategies to boost energy-efficient bulbs purchasing. Second to understand the consumers awareness levels and their behavior against the environment. Third, it intends to discern which factors affect the consumer behavior of energy efficient bulbs more than other factors. Fourth to develop a framework that reflects the main factors influencing consumer behavior for energy efficient bulbs. And finally, in order to find out which of the following factors have a positive or negative impact on the purchasing decision of energy efficient bulbs; Environmental Concern, Knowledge, Attitude, Advertisement, Eco-label, Brand or Price Concern. During the last decades global warming increased environmental pollution which resulted in a decline in flora and fauna. These are three main serious harm to the environment produced by the increase of consumer's ingestion of goods and services (Chen & Chai, 2010). Moreover, what makes the situation even worse, energy consumption also increased treme...
